Abstract RoF (Radio on Fiber) relay tramsmission link is proposed as one of usage models of 802.11aj. RoF relay link can extend wireless access area to the different location without additional requirements. RoF relay link has broadband transmission capability due to O/E and E/O broadband conversion characteristics and can transmit RF signals at 45-GHz and 60-GHz bands simultaneously. The aim of this contribution is to add a new usage model for IEEE 802.11aj Usage Models Document IEEE 802.11-12/1245r4. The contents of this contribution are based on IEEE 802.11-12/0177r4.

Usage Model 10a: RoF Relay Transmission Pre-Conditions: Wireless zones are connected via RoF relay link. The individual wireless zones can support high-speed-data traffic requirements that are limited by the VHT link capabilities. Application: Traffic is bidirectional and is comprised of subcarrier which include data, voice, video, and any kinds of signals. These subcarriers are radio frequencies, i.e. either 45GHz or 60 GHz bands. RoF relay link extends coverage areas without any performance degradation and any changes of traffic requirements. Environment: Environment can be home, office, manufacturing floor, etc. The RoF realy link distance can be extended up to 200 m due to latency of E/O and O/E conversions. Typical areas which are connected via optical fiber cables are electromagnetically isolated. No degradation of system characteristics can be managed by use of RoF relay transmission link.
Traffic Conditions: RoF relay transmission link can carry any type of traffic due to broadband transmission capability and linear characteristics of E/O and O/E devices. No additional traffic conditions are introduced by RoF relay link. Use Case: 1. Electromagnetic isolated spaces such as
rooms of houses surrounded by concretes are directly connected through RoF relay link without any digital signal processing units of relay stations.
2. In spite of physical and electromagnetic separation, one wireless zone is extended to another wireless zone through optical cables.
3. Users at different locations can take advantage of broadband multi-media applications.

Summary • RoF relay transmission link was proposed as a new usage model. • RoF relay link can extend wireless access area using E/O, O/E and optical
fiber without any additional requirements. • Data transmission experiment of RoF relay link using 802.11ad signal
were presented and EVM of transmitted signals are less 14 %. • Additional delay time caused by RoF relay link is about 350 ns at a fibre
cable length of 50 m. • Maximum length of fibre cable is about 100 m taking into account CCA
(Clear Channel Assessment). • Spurious free dynamic range of RoF relay link is improved up to 80
dBHz3/2. • 802.11ad devices will be used to transmit HD signals through RoF relay
link for evaluation and demonstration.
